Yeah, pushing current CPUs (Intel and AMD both) as far as they'll go is well into the diminishing returns. For AMD HW I'd likewise recommend using one of the "Eco" modes. The single-digit percentage points you get out of

It's an issue that, while the mainboard is involved, happens to occur on (at least) the 3 best-selling mainboard vendors compatible with that family of CPUs, at stock settings, so that you can take an affected CPU, swap it through a se

That error comes out of Unreal Engine proper, not Oodle, and is meant to be shown in cases when compressed shader data is corrupted in the game data files on disk in a way that hasn't been caught by package validation. Which is to say,

Thanks! Chance, sure, it's just a matter of logistics. Revision is a bit tricky since it's usually shortly after GDC, a very busy time in the game engine/middleware space I work in, so not usually when I feel up to a pair of

(Oodle maintainer here.) This issue only occurs on some small fraction of machines, but on those that we've had access to, it reproduces with BIOS defaults and no user-specified overclocking. It turns out several of these mainboards wi

Oodle maintainer here, we had two people that hit the issue offer to run some experiments for us. Neither were doing any overclocking before and both tried numerous things including resetting to BIOS defaults and also updating their BIOS (t

Definitely not. These are supposed to be higher-quality bins that also ship with higher stock clock rates (both base and boost) and are rated for them. I don't know how common this is across the whole population of PC buyers, but perso

This is blowing up now, but the first report of this kind of issue that reached me (I'm the current Oodle maintainer) was in spring of last year. We've been trying to track it down (and been in contact with Intel) since then. The

(I'm Oodle maintainer and did most of this investigation.) For the majority of systems "in the wild", I don't know. We had two people with affected machines contact us and consent to do some testing for us, and in both c

Dynamic switching power (i.e. the fraction of the chip's power consumption from actually switching transistors, as opposed to just "being on") scales with V^2 * f, where V=voltage and f=frequency, and V in turn depends on f,

(I'm the person who did most of the investigation.) A relatively major realization during the investigation was that a different mystery bug that also seemed to be affecting many Unreal Engine games, namely a spurious "out of vide

Absolutely, yes. It can also misbehave without any hardware bugs due to glitching. Rates of incidence of this must be quite low or that would be considered a HW bug, but it's never zero. Run code for enough hours on enough machines col

Person who actually did the investigation here. It took exactly one bug report. RAD/Epic Games Tools is a small B2B company. Oodle has one person working full-time on it, namely me, and I do coding, build/release engineering, docs
